MACHINE FOR WEAVING COIR-YARN MATS.

SPECIFICATION forming part of Letters Patent No. 630,954, dated August 1 5, 1899.

Application filed November 15, 1898. Serial No. 696,564. (No model.)

Z'o r/.ZZ whom t may concern:

Be it known that I, KENNEDY WALKER, a subject of the Queen of Great Britain,residing at London, England, have invented a certain new and useful Improvement in Machines for Weaving Ooir-Yarn Mats and Similar Fabrics, of which the following is a specification.

My invention relates to a certain improvement in machines or looms for weaving coiryarn mats and similar fabrics and may be described as an improvement on or development of the inventions described in the speciiications of United States Letters Patent No. 550,174, ofNovember19,1895, and No.612,519, of October 18, 1898.

According to the presentinvention I modify several of the parts of the machine constructed under the Letters Patent above named for the purpose of obtaining a quicker-running machine and a machine which will produce amore perfect fabric than hitherto has been possible.

In the accompanying drawings are shown my improvements applied to such a loom, sufficient of the other parts of the loom being shown to make my invention clear.

In the drawings, Figure 1 isa longitudinal section on linen v, Fig. 3. Fig. 2is asection on line w w, Fig. 3. Fig. 3 is a front elevation with the beaterornitted. Fig. 4 isa right-hand side elevation to show principally the dividing apparatus, many other parts being omitted. Fig. 5 is a section, looking also from the right hand, taken on line or rc, Fig. 3, to show the stop mechanism, other parts being omitted, and a weight forming part of such mechanism, and which is hereinafter described, removed. Fig. 6 is a section on line y y, Fig. 5. Fig. 6 is a similar View showing the parts in another position. Fig. 7 is a front elevation of the plunger mechanism on an enlarged scale. Fig. 7a is a section on line z e, Fig. 8. Fig. 8 is a plan of Fig. 7, showing the parts in one position. Fig. 9 is a plan showing the parts in the opposite position. Fig. 10 is a section, on an enlarged scale, through a part of the loom to show the thrumbox and its guides. Fig. 11 is a plan of a portion of same. Fig. 12 is a similar section with the parts in a different position. Figs. 13 and 14 are further sections to show the parts inv other positions. Fig. 15 is a detail view, on a still larger scale, to show one of the dividers forming part of the thrum mechanism. Fig. 1G is a plan showing two of said dividers. Fig. 17 is a front view of same. Fig. 1S is a detail View of one of the fingers forming part of the thrum mechanism. Fig. 19 is a plan showing two of said fingers. Fig. 2O is a section of two of the fingers on line u u, Fig. 18. Fig. 21 is a detail showing one of the delivery-bars forming part of the thrum mechanism. Fig. 22 is a front elevation of same. Fig. 23 is a plan of Fig. 21. Fig. 24 is a detail showing a divider, a finger, and a delivery-bar in one of their positions. Fig. 25 isasection of same on line t t, Fig. 24. Fig. 26 is a front elevation, on an enlarged scale, of a part of the beater and healds, together with an appliance for moving the outside warp-threads of the mat being formed. Fig. 27 is a plan of same on line s s, Fig. 2G. Fig. 28 is a side elevation showing a portion of the front of the loom andthe mat-rollingup device. Fig. 29 is a front elevation of the latter.

In the loom constructed according to my invention the warps 1 are carried between a pair of rollers 2 2, one of these rollers carrying a spur-wheel 5, gearing with pinion 4 on a stud 3, carrying a brake wheel or disk 193, for the purpose hereinafter explained. The warp is drawn down through the rollers by the operation of the mat-drawing-off device hereinafter described and passes under an idle roller 6, placed in such a position that a line drawn from the last shot weft to the under surface of the roller would pass through the center of the space through which the warps travel, so that they are taut when up and down and slacken as they approach the center. This arrangement is shown in Fig. 1, the imaginary line being drawn between the roller and the mat 7. For the purpose of making the shed the two rows of heald-rods 8 are carried by bars 9 9, each of which is suspended by two links 10 10, attached to one pivoted to the inner frame 12 of the loom and those at the other side of the loom being pivoted to a bracket 11"- of said frame. The opposite ends of the cranks are connected by a end ot' cranks 11 11, those at one side being bai-13. The healds are suitably guided by passing through a bar 14, and each bar 9 has attached to it at one end connecting-rods 15,

A work in slots 38a 38a in same.

Figs. 2 and 3, connected to levers 16 16, pivoted on a shaft 16h, carried between the inner frame 12 and outer frame 151, Figs. 2 and 3, and carrying rollers 16' 16, which work in cam-grooves 17 17a, Fig. 2, arranged on opposite sides of a disk 18, mounted on a shaft 19, which is driven by a spur-wheel 2O from a pinion 21 on a main shaft 22. The upward and downward movements of the rods 15 thus produced positively operate the healds in both directions byalternately raising and lowering the bars 9 9 and alternately raising and lowering the two rows of healds. The thrums or U shaped tufts of coir-yarn which are inserted into the fabric and which go to form the pile of the mat are cut od in lengths from the yarns 23, which are drawn or fed forward by means of a clip orgripping device 24, which is termed the back clip, such clip being mounted on a plate 25, carrying what is termed an inner Itube 26, sliding in an outer tube 27. The two tubes are connected by levers 28, pivoted to a common stud and are operated bya crank 29 on a shaft 30 through a suitable connecting-rod. The clip 24 is raised and lowered at'suitable intervals by an arm 31 on a shaft 32, and the feeding movement consists in causing the clip to be lowered to grip the' yarns and the two tubes 26 27 to move forward'together to draw od the yarns,

the forward tubes 27 stopping after a shortmovement, while the back or inner tubes 26 continue their movement, so as to project a short length of yarn out of the forward end of each tube 27 and bring it under a suitably'- operated front clip 33, which holds the end While a length is cut oif by a reciprocating` knife 34, after which the lengths so cutoff are forced down tubes 35b by plungers 35 in a doubled or U-shaped form, such plungers having a partial rotation given to them, so as to bring the loops so formed at right angles to the warp-threads between which they are about to be inserted.

All the above mechanism has been previously described'in Specification No. 612,519, and the means forgiving the partial rotation to the plungers in Specication No. 550,174. In this latter specification the means employed for giving this rotation consisted of an arrangement of spiral grooves on the plungers, which in conjunction with other parts caused the same to rotate, and instead of this I prefer to operate the plungers more positively, and to this end I employthe arrangement shown best in Figs. 7 to 9, where the top of each plunger 35, after passing through and being guided by a bar 35, has fixed to it a lever 36, carrying at its other end a pin which works freely in a hole in a transverse bar 37. The bar 37 is hung and connected to a bar 3S by pivot-pins 39, which l Said bar is held by and is capable of a transverse slidof connecting-rods46 46a, the former being attached to a lever 47, rocking on a shaft 48, Figs. 2 and 3, and carrying a roller which is operated by an eccentric groove in a disk, the

Vparts being the same as on the other side,

where it will be seen that connecting-rod 46"t is attached to a lever 47, pivoted on the shaft 48 on the opposite side of the inner frame 12, the lever carrying a roller 47h, (shown in dotted linesin Fig. 3,) which is operated on bya cam-groove in a disk 49 on shaft 22. It Awill be seen that the reciprocating motion thus -imparted will raise and lower the frame carrying the plungers and'that as they (the former) move past the fixed guides 44 a transverse reciprocating motion will be imparted to the bar 37 through the rollers 45 and bar 38, so that the bar 37 will be moved from the position shown inFig. 8 to that shown in Fig. 9, with the result that the plungers are positively and simultaneously turned.

In order to-draw the thrum or pile yarns 23 more slowly from the bobbins, so that less strain is put on the loom, whereby it may run quicker than heretofore, I arrange at the rear end two transverse bars 50 51, having a hole for each of the yarns, forming a guide for same, such bars being carried by uprights 50aA 51a. Between these bars there bears upon the yarns a transverse roller 52, carried by levers 53, pivoted to brackets 54 on either side of the inner frame 12. connected by a cross-bar 55, to which is attached a connecting-rod 56, which passes between the yarns 23 and is operated by an eccentric 57 from the shaft 22, the timing being such that when the feeding-tubes 26 27 are at work the eccentric has the roller 52 raised at its highest point and out of the way of the yarns, but as the tubes come to rest the roller is pressed down between the two guides 50 51, and thus draws off the thrumyarns ready for the next feeding movement of the tubes, which thus draw from a slack body of yarn instead of direct from the bobbins. After these lengths of yarn or thrums lOO The levers are IIO are cut off and forced down the tubes 35b by the plnngers it is necessary that they should be carried forward and placed` on the warpthreads 1, and to this end I employ instead of the arrangement of parts described inthe prior specication, No. 550,174, before referred to, the arrangement shown in Figs. 1 and 2, but on an enlarged scale in Figs. 10 to 25. This consists of a number of fingers 58. Each of these is preferably formed as a separate part and is bolted to a transverse bar 59. Each tinger has a slot 60 in its upper end and grooved sides 61, which are hollowed out slightly, as at 62, Figs. 18 and 20. The bar 59 carries near each end guide-rods 63,which pass through and are guided by a bar G4 beneath the bar 59. At each end of the bar 64 is a head or plate 65, carrying four rollers 66, the two upper ones being arranged to travel between guide-bars 67 67, and the two lower ones to work against the under side of the lower bar 67 to assist in holding the bar 64 in place. The bar further carries lugs 68, to which is pivoted a connecting-rod 69,attached to a lever 70, Figs. 1 and 3, pivoted at 71 in a bracket 70, such lever having a roller 72, which works in an eccentric groove 73 of a disk 74 on the shaft 22. The rod 69 is loosely hung in the lugs 68, so that the bar 64 may be able to take a movement laterally. The bar 64 also carries guides 75 75 at either end, through which pass rods 76, there being one at each end of the bar or side ofthe machine. Each rod terminates in a roller 77 and supports a transverse bar 78, which carries in turn a bar 79, having a hook 79, which engages with the notches in the ends of a series of delivery rods 80, Figs. 21, 22, and 23. These rods have forked heads 81, adapted to seat in the grooves 61 between each two ngers 58, the shoulder 81 of the bar resting on the bottoms of said grooves, as seen best in Figs. 24 and 25. The grooves act as a guide for the rod as well as for holding the thrums, which latterpurpose is hereinafter explained.

Between the frame 12 and having its bearings in saine is a shaft 82, having a lever 83 outside of the frame on both sides and levers 84 (one of which only is seen in Figs. l0, 11, and 12) inside the frame on both sides. The levers 84 carry rollers 85, 'adapted to bear against a transverse bar 86, carried by and slidable on pins 87, having suitable heads to form stops and attached to the bar 59. The bar 86 carries pins 88, one only of which is seen, which passes freely through the bar 58 and projects in front of same.

The shaft 82 is operated from one side of the machine, as shown in Fig. 2, from an arm 83, forming a crank with one of the levers 83, and to this is attached a connecting-rod 83h, pivoted to a connecting-rod 83, pivoted in turn on shaft 48. The lever 83 carries a roller 88, which works in an eccentric groove or cam 83e of a disk 88f on shaft 22.

The bar 59 has lugs 89 at each end, which carry rollers 90, which slide on the lupper side of the upperguide 67. Mounted on and bolted to the bar 86 are a series of dividers 91, which consist of meta-l lingers of U shape in section, their greatest depth being somewhat less than the depth of the groove 61 of the fingers 58, into which they are adapted to enter and from which depth they taper off forward into a point and preferably, as shown, rearwardly also.

The levers 88, of which there is one at each end of shaft 82, are also attached to connecting-rods 92, Figs. 1, 2, 10, 11, 12, and 13, whichl pass to one end of crank-levers 93, pivoted at 94, the other end of said levers being attached to connecting-rods 95, which are pivoted to and support rods 96, which in turn carry heads 67, forming in one of their positions, such as that shown in Fig. 10, a continuation or porr tion of the upper guide or track 67, which I term the trap. This part 67 is out of line with rod 96, as seen in Fig. 11, and in order to guide the latter it is provided with a head 98, which works in a groove 99 of an inclosing piece 100, attached outside of the frame 12. (See Fig. 2.)

Pivoted inside of the frame on each side at points 101 are two switch tracks or guides 67, one end of which is adapted to lie closely on the top of the upper track 67, while the other is provided with a pivoted latch, the head 102 of which engages with a notch in the side of the head 98 and serves to hold the track or guide G7b in position when a weight is upon it until the trap 67a is lowered, as hereinafter described. The latch has a part 102a corresponding to the head 102, but reversely arranged, and the two are connected byapart102l,the whole sliding inagroove102c in the frame. The head 67a is notched both on the upper and under sides to receive the hooked ends of the latch. The upper guide or track 67 extends only to a point where it will abut against the trap 67 when the latter is in its lowest position, but the lower guide 67 extends some distance beneath andin front of the upperguide. Beneaththelowerguide and pivoted on a stud 108 to a bracket 104 is a channel or guide 105, Figs. 1, 5, 6, 10, 11, and 12, rocked by a rod 106 through a vertical reciprocating rod 107, which is guided in eyes 108, as shownin Figs. 5 and 6. The bar 107 has an eccentric slot 109 therein, with which engages a pin 110, carried by a bar 106, so that the latter will be reciprocated by a vertical movement of the rod 107,which movement is effected from a lever 111, pivoted outside frame 12 and connected to the strap of the eccentric 112 on shaft 19.

The transverse bar 64 carries a stud 113 beneath same, having a roller 114, (shown in dotted lines in Figs. l0 to 14,) which is adapted to enter the channel or guide 105.

At the front of the loom are two xed uprights 115, Figs. 1 and 14, carrying a sloping table 116, on which the mat rests as it is being formed, and at the lower ends two sloping iixed guides 117, against which the rollers 77 of rods are adapted to strike.

The operation is as follows: The plungers 35 force the cut-otl thrums 118 through tubes b into the grooves 61 between the fingers 58, where they seat on the upper side of the shoulders 81a of heads 81 of the rods 80, the parts being in the position shown in Fig. 10. The plungers next begin to retire and the rotation of the shaft 82 through the levers 84 forces forward bar 86, thus thrusting the dividers 91 between the lingers 58 and the forked ends of the rods 80 until these particularparts IOO IIO

abling this to be done.

are in the position vshown in Fig. 24, so that the thrum 118 is held securely in place and is also kept open. The levers 83, also through rods 92, cranks 93, and connected parts, raise the track-pieces 67a, which thus raise and latch the switches 67", bringing all the parts into the position shown in Fig. 12. The rod 69 now begins to move bar 64C forward between the guides 67 and the roller 114 engages the lateral motion guide or channel 105, which moves same to give the ngers the position desired. This is effected by moving the channel 105 into the dotted position, Fig. 11, on the right hand of the central position, so that the roller 11a is caused to move to one side, thus drawing the rollers 66 and 90 farther out on the guides 67, which are made wideenough for the purpose, and shifting' the bars 64, 59, and 86 laterally, so that at the end of the forward movement they are in such a position that the thrums carried thereby are placed on the Warps which have previously been the idle Warps. As the parts move up such guides 67 the roller 90 of the bar 59 travels on the upper side of the upper track 67 until it meets the switch 67", when the bar 86, together with bar 59, rises up on same until the parts are brought into the position shown in Fig. 13, where it will he seen that a slight separation of the bars 86 and 59 has taken place by reason of the upward movement of bar 59, so that the dividers 91 have commenced to leave the fingers 58. The grooves 60 of the fingers have also raised and separated the idle warps, the amount of slack in same due to the position of the healds at this point en- The movement has also lifted the delivery-bars 8O by means of their heads, which are held in the fingers 58. The further forward movement of the parts results in the rollers 90 arriving over the trap 67a, at which moment the rollers 77 are on the top of the inclines 117 and the deliverybars 80 are held up, the thrums being then around each alternate warp 1, the forked ends 81 embracing the warp and separating them from the idle warp on either side. Previously to this operation, however, the pins 88, carried by bar 86, have come into contact with the uprights 115, and thus the bar 86 and dividers 91 have been forcibly driven back to clear the fingers, so that they may fall and leave the delivery-rods. Almost simultaneously with these two operations the connecting-rod 92 is operated to draw down the trap 67a through crank 93 and connected parts, and the bar 86 consequently falls with it until the part or trap 67L is level with the upper track 67. The trap in its fall strikes the end 102 of the latch, and thus opens the switch 67h, so that the parts are then allin the position shown in Fig. 14C, the fingers 58 having dropped also and lowered the idle warps, while the healds have raised the other warps on which the thrums have been put and formed the shed for the weft. As soon las the backward movement begins the delivery-rods drop', leaving the thrums on the' warps, and the parts move backward down the tracks or guides 67 67, the bar 86 maintaining its distance from the bar 59, so that all the parts move back into the position shown in Fig. 10, the guide 105 being for the next forward movement shifted to the opposite position, so that the' rollers are forced farther'in on guides 67, and the parts will travel forward in a different line at the next feeding movement.

It will be understood that the healds separate the warps in the usual Way to form ashed,

and that between each delivery of the thrums there is a shot of weft put in by a suitable picking mechanism, which forms no part of my present invention, and that the fabric is also beaten up by the reeds 119, Fig. 1.

In place of the arrangement for operating the front clip, which is described in the speci- Iication of Letters Patent No. 612,519, I employ the arrangement best shown in Figs. 3, 5, 6, and 6. ln this the clip 33 is hung on a fixed transverse bar 120 by means of cranks 121, which are pivoted at 121, and are connected to them by links 1211. these cranks is shown in Figs. 6 and 6"; but the arrangement is the same at the other end. The upper ends ofthe cranks 121 are pivoted to a transverse bar 123, one end of which projects outside the frame 12 and is connected loosely to a lever 124, pivoted to one end of a shaft 125, carried in bearings 125 on the outside of the frame 12. The other end is suitably guided. Also connected to the bar 123 on the other side is the inner end of a crank 126, the outer end of which is notched, as indicated in Fig. 6, and is adapted to be caught by the hooked end of a connecting-rod 127. The crank is pivoted at 126a to the frame 12. A spring 128 tends to draw the outer end of the lever 126 upward and thus keep the clip raised. The outer end of the lever 126 has a downwardly projecting extension 1261, against which the hooked end of rod 127 mayrub when it is out of engagement. The other end of shaft 125 carries a hook 129, adapted to engage at intervals with an arm 130 on the shaft 32, which operates the back clip.

The rod 127 is connected to alever 131, having a roller 132, pivoted on shaft 48, such roller engaging with an eccentric groove or cam of a disk 133, mounted on shaft 22. The upand-down motion imparted to rod 127 draws down crank 126, the spring attached to the latter assisting it to rise, and it thus reciprocates bar 123 and front clip 33, the bar 123in turn, through lever 124, rocking shaft 125 and hook 129.

For the purpose of stopping the operation ot' the clips both from front and back, so that the thrum-yarns are not drawn o when the mat has been finished or it is otherwise desired to throw the thrum feeding and spinning mechanism out of gear, I connect to the rod 127 a rod 131, Figs. 3 and 5, and to the other end of the rod 131 I pivot one end of a Only one of IOO IIO

handled lever 132, which can rock on a shaft 133. The rod 127 is connected to rod 131. by means of a pin, which can move in a slot 131b of rod 131. The rods 131 and 127 are further connected by a spring 131, the effect of which is to draw the rod 127 to the forward end of slot 131i. The extreme forward end of the rod 131 is notched, and with the notch engages a latch 134, the purpose of which will be hereafter explained. After lifting this latch the handle may be drawn forward and the rods 131 and 127 forced backward, thus disengaging the hooked end of rod 127 from the lever 126, which is thus drawn up by spring 128, so that the front clip remains raised, while the hook 120 is also held in its forward position, and consequently will prevent the arm 130 on shaft 132 from rising, so that the back clip,which is raised bya spring, (as described in the specification of Letters Patent No. 612,510 referred to and the operation of which does not form p art of the present invention,) is held down. In this way the clips are both prevented from straining against each other ,and the feeding is stopped, as the back clip,

though it has the yarn gripped with the right length projecting through the tubes, simply moves backward and forward and does not draw oif any yarn, and there being no resistance at said back clip the roller 52, though it continues to operate, is unable to draw olf any yarn.

For the purpose of measuring the mats as they are made and automatically stopping the feeding of the thrums l employ the following arrangement: ln the front of the machine between the pairs of drawing-off rollers 135 136 137 138 and at one end of saineisa slotted rod 140, Fig. 3, which is attached to a slotted rod 141, pivoted to a lug 142 inside one of the frames 12, the two rods being so secured together as by a nut and bolt or otherwise that the rod 140 may be readily removed laterally to be adjusted to the width of the mat being made. The rod 140 carries a projection 143, which is adapted to be struck by a finger 144, carried by the mat, which is shown in dotted lines 145 in Fig-3. This finger consists of a piece of metal which is inserted between the warp-threads at the beginning of each mat. The rod 140 is also adjustably attached to a transverse slotted lever 146, pivoted at 147 to the opposite side of the frame 12 and capable of rocking on said point 147 and being formed with an extension 146, carrying an adjustable balance-weight 148, which tends to keep the opposite end of lever 146 raised. To the part 146a ol'lever 146 is pivotally hung a link 149, pivoted to the free end of latch 134, which is pivoted in turn to lng 150 on the inside of the outer frame 151. lt will be seen that as the mat travels down between the rollers 135 to 138 the linger 144 will strike projection 143 and draw down lever 146, lifting the end 146 and raising the latch 134, with the rcsult that the spring 131iI will draw back the rod 131 and force the hooked end of rod 127 off the lever 126, and the clip will thus be kept raised. The parts are restored by the handled lever 132, by which the rod 131 is moved forward and through the spring 131'LL draws forward rod 127, so that the hooked end of rod 127 is drawn against the extension 126b of the crank 126, and as such rod is always reciprocating vertically it will engage the crank 126 and begin to operate it again. The catch 134 is restored by the weight 148, which also puts the lever 146 back again into the saine position for the next mat. The object of the slot 131b in the rod 131 is to allow rod 131 to be drawn forward to engage withl the catch irrespective of whether the rod 127, to which it is attached, is at the top or the bottom of its stroke.

It is desirable when a mat is finished and a division is required between it and the next mat to draw it down quickly, together with the warp-threads which constitute said division, and for this purpose Isecure to the lower rear drawing-olf roller 138 a sleeve 152, Fig. 3, movable with it and surrounding the shaft 133, which merely forms a support for the sleeve and is -not attached to the roller. The sleeve 152 carries an arm 153 and springpressed pawl 154, Figs. 4 and 5, which bears against a ratchet-wheel 155, Figs. 3 and 5, secured on shaft 133. The shaft 133 turns in bearings on frame 151 and terminates in a worm-wheel 156, operated by a worm 157 on a shaft 158, suitably supported in bearings outside the frame 151. At the other end of shaft 158 is a bevel-wheel 159, gearing with a similar wheel160 on a shaft 161, carried in a bracket 162, projecting at right angles to the frame. The shaft 161 carries a sprocketwheel 163. The sleeve 152 carries'a sprocket- Wheel 164, which is driven, by means of a chain, from a sprocket-Wheel 164@ on the shaft of the upper front roller 135, so that as the latter is driven by the drawing through of the mat the roller 137 is also driven. The back rollers 136 138 are also provided with sprocketwheels 164b 164, connected by a chain, and the roller 138 is normally driven by spurwheel 207, Fig. 2, on the opposite side to ratchet-wheel 155 through a wheel 208, carried in a curved slot 209 in a bracket attached to frame 12. The slot corresponds to the center of wheel 207. The wheel 208 is driven by a change-wheel 210, carried on a stud 211 in a suitable bracket, Fig. 5, of the frame, and such stud extends through inside the frame, Fig. 3, and carries a ratchet-wheel 212, driven by a pawl 213, hung on an arm 214, pivoted on stud 211. By substituting other wheels for wheel 210 a change in speed is effected. Connected to arm 214 is a rod 215, operated by an eccentric 216 on shaft 22, the reciproeation of the rod 215 giving, through the ratchet and pawl, an intermittent movement to the parts. 0n the shaft 161 is pivotally hung a lever 166, the upper end of which forms a bearing for the spindle 168 of a pulley 167, the other end of the spindle 168 be- ICO IIO

ing carried on an arm 169, capable of rocking on the shaft 161. The spindle 168 carries a sprocket-wheel 1635*, which is connected by a chain with the wheel 163. The lower end of lever 166 is attached to an adjustable connecting-rod 170, connected to a crank 171, the opposite end of which carries a weight 172. The crank is pivoted on a shaft 174, supported in bearings between the inner and outer frames, Fig. 3, the inner end of such shaft 174 having an arm 173, secured to it, connected to a rod 176, attached to apivoted foot-lever 177 in the front of the machine.

Supported in the frames 12 and passing also through the right-hand side frame 151 is the d riving-shaft 178, carrying fast and loose pulleys 179 180, the former being driven by belt 181. Supported on a stud in a bracket 182, attached to the frame 151, is an idle pulley 183, which is located inside the belt 181. The

shaft 178 carries a pinion 184, which drives a spur-wheel 185 on shaft 22, which shaft carries the pinion 21, Fig. 1, which gears with spur-wheel 2O on shaft 19. The upper end of the lever 166 carries a cord 187 which passes over pulleys 188 188 188, hung in brackets on some Xed point, as the ceiling, and in a bracket on frame 151,1espectively. The other end of the cord is attached to a counterweighted lever 189, having a cranked end 190 and pivoted at 191 to frame 12. The end of the cranked portion carries a brake-shoe 192, which bears against the rim of a disk 193 on stud 3. The operation is as follows: The roller 138 is driven intermittently, as described, and through the sprocket-wheels (and chains) 164:c and 164b the upper roller 136 is driven, the

friction of the mat passing through, driving in turn roller 135, the sprocket-wheel 164a of which, through the chain, drives the sprocketwheel164 of roller 137. The motion thus transmitted to roller 138 rotates the sleeve 152, the pawl carried by which travels around the ratchet-wheel155 without operating same. As soon, however, as it is desired to pull off the mat directly and quickly the foot-lever 177 is pressed down, (afterstopping the thrum-feeding mechanisn1,) thus rocking lever` 166 on shaft 161, pulling cord 187, raising lever 189, and so removing the brake 192 from disk 193. The brake is otherwise normally on to give the necessary drag to the warps passing between rollers 2 2. The warps are by this means enabled to be drawn through freely. The continued movement of lever 166 brings pulley 167 against belt 181 and presses it.

vagainst the loose pulley'183, (which acts as a support,) and the pulley 167 is thus driven, and drives, through sprocket-wheels 163l and 163, shaft 161, which in turn drives, through bevel-gears 160 and 159, shaft 158, which, through worm 157 and worm-wheel156, drives shaft 133 and ratchet-wheel 155, which thus overtakes the pawl 154: and commences to drive sleeve 152 and roller 138 continuously.

For the purpose of making a mat having good wearing qualities and presenting a welliinished appearance it is desirable that the outside warps on each side receiving thrums should carry a close series of such thrums, which will not be the case if they only receive a thruin alternately, as would be ordinarily thecase. Ithereforeprovideanarrangement (shown in Figs. 26 and 27) by'whioh the out# side warps will receive a thrum each time. These two outside warps 1a 1n are passed through guides 195 195, each of which, as shown, may consist of two fingers attached t0 a plate 196, secured to a transverse bar 197, suitably supported in guides 198 198, Figs. 1 and 3, on theinner Vframe 12 and capable of sliding therein. The lingers are adjustable on the bar by means of holes 199 and corresponding holes in plates 196, through which holes pass suitable bolts. The end of the bar carries a roller or pin 200, engaging in a slot 201 in the bar 107, (see also Fig. 5,) so vthat the reciprocation of the latter will slide lthe bar 197 to and fro, its movement therefore corresponding with the rocking of the channel 105, which eects the lateral movement of the thrum-carrying fin gers. The beater 119 lis carried in the usual manner by the slay, (which it is not necessary to show,) and the numerous reeds which go to make up same are carried in the upper and lower bars 201 202 of same, respectively, by rods 203 204,on which they are threaded,each rod beingsea'ted in a groove in the bar, as shown in Figs. 1 and 26, and passing through the endsof the reeds, which are separated by washers 205.

In this way by withdrawing the rods one orV more of the reeds can be removed and a larger washer 205a inserted in their lace leavinoawider gap between the reeds for the warps 1a 1a to pass through and allowing them room to be reciprocated by the movement of the bar 197, as shown in Fig. 27.

It is desirable to provide a selvage for the mat in addition, and to this end a further warp 1b 1b is used at the extreme outside, such warp receiving no thrums, but only being held to the mat by the weft-thread, which bends around same. These threads 1b 1* are passed between reeds 119, which are out of a straight line with their healds 8, as shown in Fig. 27, so that room is allowed for the warps 1fL 1a to be reciprocated. The operation is as follows: )Vliere referring to Fig. 27 and commencing from the "left hand it will be seen that the warp 1fL has been moved out of the straight line, and referring for the purpose of explanation to the warps by the letters a b c d et b c d it will be seen that a thrum will be put on the alternate warps a I) CZ and so on, and on the other side'on the alternate warps ct c and so on, the shifting back of the bar bringing the warps 1a into the position shown in dotted lines, when the thrums will be put on the alternate warps a c and so on, and on the alternate warps on the other side ct' b' CZ and so on, the warps 1 la a ct') always receiving a thrum by reason of their being caused to follow the movement of the thrumfingers, which come up from beneath the warps, as previously explained.

In connection with the measuring device it has been found desirable to keep an even strain on the mats as they pass through the drawing-off rollers, as otherwise they may bend or curl, and thus the finger 141i may miss the projection 143 or strike it late, and, further, it is desirable to take away the mats and coil them up as they are made and before they are separated. To this end I employ the arrangement shown in Figs. 2S and 29, in which the arm 214 is connected to and operates a rod 217, having a slot 217BL in its front end, with which engages a pin or stud of a lever 21S, pivoted in a frame 21S) and carrying at its other end a pawl 220, engaging with a ratchet 221 on the shaft of a roller The roller has lugs 224C at each end, through holes in which passes a rod 223, by means of which the first mat may be attached to the roller 222, the rod being first withdrawn and the mat placed on the roller and the rod replaced. A pawl 225 prevents the roller turning backward. To the end of lever 21S is attached a spring 226, the other end of which is secured to frame 12 of the loom. As the rod 217 is drawn back, the lever 218 by the action of the spring will follow same, the slot 217a allowing a larger movement to the rod 217 than is necessary for the movement of the lever 21S and pawl 220, which is controlled by the amount of mat it is able to draw off. As this is very small, the forward movement of the pawl is slight. Its backward movement is effected by the forward movement of rod 217 when the end of the slot 217 engages the pin of lever 218. The mats 7 leave the loom by passing under a roller 186 and pass up to roller 222 around a roller 227 on frame 219.
